JNI调用本地库时JAVA虚拟机异常退出问题定位，通过虚拟机生成的hs_err

本文主要是介绍JNI调用本地库时JAVA虚拟机异常退出问题定位，通过虚拟机生成的hs_err_pidxxx.log日志文件定位过程，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

JAVA代码中有一处需要通过JNI调用本地的DLL库，每次一到这里整个程序就直接闪退，程序目录下有生成的虚拟机日志文件hs_err_pidxxx.log，相同的程序运行在别的机器上都没有问题，刚开始无从下手。

1 开始慢慢分析hs_err_pidxxx.log文件，日志的第二行EXCEPTION_ACCESS_VIOLATION ，发生这样的错误，大多是JNI端代码有问题，如：不恰当的 printf 及 cout 调用，方法调用类型不兼容，调用被销毁的对象等。可是在别的机器上程序运行又都是正常的，说明JNI部分的C++代码应该也没问题

2 下面把注意力放到了msvcrt.dll这个文件上，在环境上搜了一下，msvcrt.dll这个文件有N多个，而且大小各不相同，这里开始怀疑是不是动态库加载的顺序出了问题，接着发现这台电脑上安装了多个版本的程序，其中的JDK库和程序自己的相关DLL库文件都不一样。

3 之后把程序的path路径修改了一下，把程序自己的DLL目录放在了最前面，重新运行程序，一切正常了。

hs_err_pidxxx.log文件开始
